A Shark Attack on Dressrosa
X❖X

After fighting off Hody, Luffy and the others were celebrated by the people of Fish-man Island. However, from the darkness, the little disgusting swamp-man Luff did not remember the name of, and this guy tried to attack Wimpy Hoshi. Just when Luffy kicked him out towards the kingdom below, Nami said the guy had all the treasures of the Palace with him. And so, Luffy was responsible for bringing the treasures back. Zoro and Sanji, who were with him, were forced to accompany him.

However, once they approached the city, there was a commotion.

"Lady Praline, how nice it is for you to be here."

"Hmmmmm? Shashashasha… I don't think we have time for pleasantries. We need to fix this fast. Mother is going to be really angry about this situation."

Praline was a tall shark mermaid, and she was a hammerhead shark variant and had sharp teeth. She had cute freckles on her face and had big breasts. So big it almost spilled from her rosy cloak. Her blond hair was made into buns that resembled a hammerhead, and she had heavy eyeshadow, to say that she was dangerous. Yes, she was half-mermaid, half-human, a daughter of Charlotte.

Zoro took Sanji after he freaked out about the mermaid's beauty. Leaving Luffy alone to deal with the situation. And when Luffy is left alone, bad things happen.

This was why there was a shouting match between Praline, Luffy, and Big Mom about Fish-man Island and how the situation would be dealt with. Big Mom, through all the commotion, came with a devious plan. One that she would be able to acquire both the Straw Hat crew and still having control over Fish-man Island. Big Mom would be using Praline instead.

A betting match.

Obviously, Luffy's competitive streak flared when Big Mom wanted to make a bet, betting the island. If Luffy won, he would have Fish-man Island, as well as Praline as a bonus. However, if he lost, then the Straw Hats would have to work for Big Mom instead. Luffy would rather die than work under someone else. But the appeal of winning a bet, winning over an Emperor swayed him. He accepted the bet with his usual grin.

And the bet:

Take Praline, the shark mermaid. And another mermaid to bed and have sex with both for more than an hour. If Luffy couldn't last until then, Big Mom would win the wager. Big Mom was aware of the news, and it portrayed Luffy as a naïve brat who didn't have any idea of how the world worked. Big Mom realized the fool never had sex once in his life. This would be easy as pie.

"Sex…?" Luffy tilted his head in thought.

Big Mom laughed behind the call. Your grandson is dumb as bricks, Garp.

"Straw Hat, if you don't follow the rules, then you're not going to get your territory. A brat's a brat, after all. I thought you were 19, and you still don't know what sex is. Hahaha Mamamama..."

"Shashasha... I welcome you in my bed, the man with the Straw Hat, Monkey D. Luffy..." Then Praline approached with her boobs jiggling. This mermaid was tall. She was about eight meters tall. And was a hammerhead shark mermaid.

"Then, I need to select another mermaid for this challenge, right? And if I win, this becomes my territory."

"Yeah, also we will be recording your little session, no cheating. My daughters and I will be delighted to see what a quick shot the new rookie is."

"I see, then should I call Wimpy Hoshi?"

A woman approached him.

"No need to do that, Monkey D. Luffy." Shyarly from the Mermaid Cafe stopped him from being released from Praline's hug. Shyarly arrived from behind him with her usual deep voice.

Luffy was sandwiched from behind by another shark mermaid. Both incredibly smooth breasts mashed against each other, Both were shark mermaids of the same side, and both had their nipples poke their skin-tight coats. They wore no undershirt, so their midsections were bare to the world. Praline had dirty blond hair, and Shyarly had black hair. Both stared dominantly at the other women, as Luffy could barely breathe between this heaven of boobs.

They convened at the Palace, where Luffy and both shark mermaids were offered a room. This was a crucial moment that would decide the fate of Fish-man Island. However, Luffy felt confident. The rest of the crew were exasperated at his innocent naivety as he was basically dragged by the huge shark mermaids into their room. Where a big bed was laid out.

"What, so I just have to sleep with you both for an hour? That's easy."

Luffy bragged while crossing his arms with a big smile. Shyarly was at Luffy's side. She knew he needed someone more experienced than Princess Shirahoshi for this. Her objective was to make him last more than an hour. That meant he could not become soft before then. Praline's aim was to make him suffer the fastest orgasm, making him lose before then. If Praline won, she would have Straw Hat, one of the most celebrated rookies as her husband, and then the might of the Straw Hats would be Big Mom's to command. This was a devious wager.

However, to their surprise, Luffy ripped off his clothes. With a severe king-like look. This was the man with the Supreme King's Haki, and his presence made them both weak in their fins. Their pussies started trembling, and they started gushing out juices in excitement.

"That's a big thing you got there." Praline said as she enveloped Luffy's manly body with her long tail, pressing her boobs on his shoulder. Shyarly approached from the front and started touching his chest and his scar with her fingers. Praline kissed him from behind while Shyarly began licking his chest and went down. Shyarly arrived below and caressed the clothed member, then she pulled down to a surprise.

His cock was huge, and his balls were full. His cock was a beast in size. Maybe it was 8 or 9 inches long while soft. Shyarly didn't know he was hiding such a monster in his shorts. His ball sack was so big both balls fit into her hands. They were churning and wanting to breed her. Shyarly never got so excited like this in her life. Her pussy was leaking out and staining her tail. Then, the soft fuckstick started to get excited. It started rising and twitching, bit by bit. Luffy was still kissing Praline's huge breasts as his cock grew up to his chest. Passing his abdomen and making Shyarly gape, his cock had risen to its full mast at 16 inches. His massive cock twitched and hit his chest as the foreskin cleared and revealed his angry red tip. And below it was the accumulated dick cheese that made both women moan at the smell.

Shyarly lost the reason why she was here, and her tongue started licking his balls. While Praline smirked and attacked his tip, lapping up all the accumulated dick cheese with her tongue. She swallowed it all and went straight for the attack. She sucked his tip hard, making him stretch himself backward in pleasure. Shyarly's goal was not to make him soft but to help him stay hard for the whole duration. And yet, she forgot all that due to her unbidden lust. Praline was also very horny as she sucked and rounded his tip with her tongue. Then she showed her teeth to him. One wrong move and that sharp tooth would make Luffy have a bad day. However, Luffy smirked and applied a strong Haki to his cock, making it pure metallic black in color. Luffy grabbed Praline's blond hair and then forcefully pushed her head down to suck his cock. Her teeth couldn't break the skin anymore, so Luffy had no worries and just felt the sharp teeth tickle and pleasure him instead. No worries if she was a shark mermaid. Shyarly had the go-ahead to suck his balls as well, so she did. She was also worried about her own teeth, but Luffy just grinned. This supreme man was without any fear.

Luffy just kept fucking Praline as his cock made an extensive outline in her throat. Praline felt his massive cock and the intense smell and taste of his pre-cum as it went up and down. Her job was to make him soft. But he wasn't going down. He was going full-stop, without cumming. And instead, it was Praline who was cumming as well. She always thought she was dominant and made others subservient. However, now she was being used as an onahole for Luffy's pleasure.

"Shishishi, this feels great. Come on, the women of Amazon Lily could handle it better even though they were all virgins."

Luffy was dominating her. She felt faint as her pleasure got higher and higher, the more she was choked by his massive cock. Even though her jaw was trying hard to contain his cock into just her mouth, the more she felt faint. Her eyes rolled over as she came. She fell onto the bed as she breathed hard. Her pussy was already staining everything around with her clear liquid.

"Hey, are you alright? Maybe I went a little too far."

The man with the Straw Hat arrived by her side, concerned. Why would her enemy be concerned with her? She was trying to get him to fail, so her mother would have a more considerable fighting force. If he lost here, he would be a slave to Big Mom. Her heart raced at his concern for some reason. She turned her head to the side.

"N-No, let's continue. I'm fine."

"Oh, okay."

Luffy pointed his still-hard cock into her slit. She looked a bit frightened but then gulped and waited. The tip spread her folds like a big circle, and she groaned as she came. Just as it entered, it was such a massive cock that she didn't know if she should take it. Finally, the metallic sheen was taken out, and his color returned to the standard skin color. However, it was similarly hard, and spearing her, she felt her stomach bulge as he buried himself.

"Is it already in?"

"Yeah, halfway."

Halfway?

Praline arched her back as she came again and again, her juices bursting from her pussy and staining his cock and his ball sack. Luffy was already attacking Praline's breasts, and her tits were generously squeezed. Her big boobs were bigger than his head, so he could rest in her chest as he kept pumping inside of her. She thought he would be a quick shot and end it quickly, but instead, it was her that was falling behind. Praline had to get her bearings quickly. However, there was a cloud of pleasure that wouldn't leave her. She started getting blurry vision as her brain became addicted to the cock that was going inside her.

Shyarly, on the other hand, was also lost in the fever and kept demanding attention by nibbling his ear, so Luffy would kiss her instead.

He's thrusting, so wildly, what a thoughtless beast~. Praline moaned as she became one with her pussy. All she could think of was that cock pounding her, spreading his pre-cum uncontrollably inside of her. She felt a bit bad for her mother but too bad, now she was in heaven, she would mind if she lost to this man, this beast of a man~. Honestly, she wouldn't care if he bred her like this, right here.

And so, he continued fucking her for thirty minutes until she passed out.

"What, you are already done? I didn't even cum once." Luffy complained with a competitive streak and glee in his eyes. His supreme King's Haki rocked the room as Shyarly felt herself being dominated by this aura and her mind pledging immediate allegiance to him. Praline's well-fucked pussy trembled at his aura and rocked her again, making her have three orgasms before it subsidized. Her body was thoroughly enslaved by his will and his massive cock.

His cock was twitching powerfully, calling for another woman to breed. Charlotte's daughter could not keep up with this beast of a cock, and this wild man. Shyarly was the prime target. Luffy pushed the shark mermaid down, the madam of the Mermaid Café. Then he opened her folds with his massive member, making her suffer through a similar fate of endless pleasure. His breeding fuckstick made itself welcome inside of her.

"How does it feel? I just slammed it right into your womb. You have such a weak pussy. It opened right up as I inserted, gladly welcoming my cock."

Luffy was different from the naïve optimistic self that loved food and parties. This was his serious mode, where he conquered his enemies. However, instead of a battle, it was through sex. His will was not to be undermined by anybody. Not some mermaids who didn't have as much freedom as he had. He's a rubber man, so even though he was breeding them, he was showing them that he was all the protection they needed.

"Hgnnn~ Ahh~. Please, please more."

I'm cumming~. I'm cumming~. I'm cumming~. I'm cumming~. I'm cumming~. I'm cumming~. I'm cumming~. I'm cumming~. I'm cumming~.

His cock was so impossibly big, and yet he kept pushing inside of her, unabashed by her complaining and only caring about thoroughly dominating her and taking what he wanted. He fucked her for more than an hour. Passing cleanly through the specified time without cumming even once. And after that, he unloaded his first cumshot of the night inside of Shyarly, thoroughly filling her womb until no space was left. Her womb was filled with his cock milk as it leaked out like a gushing waterfall as he kept pumping thick ropes until it bred her very well. Shyarly felt her eggs being fertilized by his seed. His invading hot baby batter had conquered her womb for himself.

Luffy looked at Praline. She was recovering from the first sex session, though she was still drooling, and her eyes still contained hearts. She was gathering her bearings when suddenly Luffy took her mouth by surprise and pushed her down again. Praline didn't even know she had lost, neither did she care. As his cock entered her again, she felt the warmness that was missing returning, and feeling that massive cock inside her again was bliss. Praline kept kissing him until he came yet again. This time, inside of Praline, again, his potent seed had made its quick conquest. He had bred a daughter of Charlotte with his son or daughter. Just like he did in the last two months of his stay in the Calm Belt with the women of Amazon Lily.

However, the future King of the Pirates wasn't done. He kept thrusting inside of her without stopping, even as he deployed his navy into her. And afterward, the day and night consisted of him periodically changing between Shyarly and Praline in a threesome, making them go into a coma of pleasure before thrusting inside of the other. The bed kept getting wetter as his semen leaked out from the girls and formed puddles of hot steamy semen that bathed their skins. And once twenty-four hours had passed.

"Huff… That was great." Luffy cleaned his sweat as he looked at the two shark mermaids in his bed, their tall bodies were stained with his marked seed, and their pussies were trembling for more. However, both girls weren't in a state where he could continue. And he was getting hungry and sleepy at the same time. So, for now, he stopped. Thankfully his massive cock subsided. He was also stained with the girl's love juices and his own. So he was pretty filthy after a while.

Big Mom and her daughters were shocked when the first hour passed. Big Mom clenched her fists hard at how she lost her bet. However, it still could be salvaged. The brat was still big on his naïve sense of responsibility.

However, her daughters and a few gay sons were having other thoughts. They brought their own Transponder Snails into their private rooms and watched the sex live, projected on their walls. They masturbated all day as the sex continued. After things were over, they begged Big Mom to let Straw hat Luffy into the territory.

Luffy was sweaty and covered up to his midsection in semen. So he went to a large bath as he left the two shark mermaids having post-orgasm from the sex. Sometimes their pussies would cry for more and tighten, sending them into a loop of orgasms. Almost like his large cock was still pounding them, phantom orgasms that continued even after a full day had passed. Luffy, however, enjoyed himself in the bath.

Luffy went back into the room and felt himself growing hungry for meat. He looked at the Transponder Livestream, and then he laughed brightly, with the towel on his shoulder. "Shishishishi… I guess I won our bet, Big Mom. Now Fish-men Island and Praline are my property, right?"

Zeus and Prometheus were raging, but Big Mom was still calm, despite the veins popping in her fists while having fantasies of her own involving her younger self and that high-caliber man. "Yes. However, this isn't the last of our bets. Come, to the New World, I still have 38 daughters left to bet."

"Oh really?"

"There is still more and more left. Our battle is still not over. And by the end, I'll have you, Straw Hat… Hahahaha, Mamamama."

"Shishishishi."

Both contenders for the One Piece laughed, while the Straw Hat crew looked on either gushing or fuming with rage.

Elsewhere another snail saw the events that unfurled on Fishman Island. This Snail belonged to Kaido of the Beasts. He was looking at the footage with an out-of-character smirk on his surprisingly sober face, with Black Maria giving her undivided attention to his raging boner.

"I don't know what a Monkey D. wouldn't do. It seems like Linlin bit more than she could chew."

In the end, Luffy conquered all the young unmarried daughters of Charlotte, including Smoothie and Pudding, and they ran away and eloped with Luffy's crew.
